Background: Molar Incisor Hypomineralisation (MIH) is a qualitative defect of enamel mineralisation with worldwide presence. In India, most data has been have been published from North and South India and not much data has been published from West and East India. Aim: To estimate the prevalence, defect characteristics and severity of MIH among children of Pune, Maharashtra. Method: This cross-sectional study included 1080 children in the age range of 8-12 years, studying in Zila Parishad Primary Schools from Pune, Maharashtra, India. The dental examination was conducted for the diagnosis of MIH by a single well-trained and calibrated pedodontist in day light conditions using the EAPD 2003 criteria. The teeth were examined in wet condition. The data was collected and recorded in MS excel sheets and subjected to statistical analysis.Statistical Analysis: All the analyses were carried out using Statistical Package for the Social Sciences (SPSS) 22.0 version (Chicago, Inc., USA). To compare the dichotomous variables Chi-square/Fisher exact test was used. P-value of

Background : Extractions are frequently used to treat crowding, protrusion of teeth and the soft tissue covering. The common consequences of extraction therapy were believed to be “dished-in profiles”, constriction of dental arch, and increased width of the buccal corridor space, whereas non extraction treatment results in poor stability and protrusive profile in borderline cases. Aim: Aim of the present study was to compare the cephalometric soft tissue changes between Class I malocclusion patients who were treated with first premolar extractions and Class I malocclusion patients who were treated with non extraction with similar appliances. Methods and Material: It is a retrospective study were the treatment records of 50 (25: extraction and 25: non extraction) orthodontic patients with Angles and skeletal Class I malocclusion of age between 13-30 years were randomly selected. Both pre and post treatment lateral cephalograms were traced manually and soft tissue changes were measured and analyzed between extraction & non- extraction group. Statistical analysis: Independent samples t test, Paired-t test. Results: Within extraction group, Angle of convexity, Upper lip to e-line, lower lip to e-line, nose prominence and interlabial gap are the parameters which has shown statistically significant(p=.000*)difference after the treatment and within the non extraction group upper lip thickness was the only parameter which has shown statistically significant (p=.005*) difference after the treatment. The remaining parameters have not shown any significant difference Conclusions: Profile improvement was better with extraction protocol compared to non-extraction therapy. Lip competence was better achieved with extraction therapy Overall the choice of the treatment modality depends on the severity of the problem.

After the introduction of cephalometric radiography, orthodontists have been using cephalometric analysis to plan orthodontic treatment and to evaluate the treatment results. For cephalometric analysis, Sella-Nasion plane and the Frankfort horizontal plane are considered as stable horizontal reference planes. Unfortunately, measurements based on the Frankfort horizontal plane do not always correspond with clinical examination. Therefore, the use of the true horizontal line (THL) and true vertical line (TVL) as alternatives seems to be advisable. This study was done in order to compare and evaluate the changes in natural head position in patients who underwent maxillary Lefort I osteotomy and mandibular set back orthognathic surgery. Thirteen pre treatment(T1) and post treatment(T2) lateral cephalometric radiographs were collected. The T1 lateral cephalometric radiographs were taken at the beginning of the treatment, and the T2 data immediately after the removal of the orthodontic appliances. The patients were instructed to stand in their natural position. 9 landmarks and 6 reference planes were traced. Results showed that Class I patients who had received conventional orthodontic treatment showed a minimal or no change in their NHP, but some Class III patients showed a change in their NHP,which tended towards head extension. Patients who have undergone Lefort I surgery and BSSO set back have shown the changes in their natural head position the differences were in their SNA, SNB, ANB, Facial contour angle and Frankfort horizontal plane angle.

A 7-month-old girl with congenital cytomegalovirus (CMV) infection underwent an immune assessment in anticipation of Transfer Factor therapy. She had been symptomatic since birth, with jaundice, rhinorrhea, diarrhea, pneumonia, hepatosplenomegaly, chorioretinitis, hydrocephalus (for which she was shunted), motor retardation, and failure to thrive. Her sputum and urine cultures were positive for CMV and her IgM anti-CMV antibody titer was positive at 1:16-1:32 dilutions. Her baseline immune assessment was normal except for a failure of her peripheral blood mononuclear cells to produce migratory inhibitory factor in response to CMV antigen. Treatment with transfer factor prepared from CMV seropositive donors resulted in clinical improvement, clearance of the virus, normal migratory inhibition factor responses to CMV antigen, and subsequent development of normal growth and development parameters.

Pharyngeal perforation is a rare serious finding with fatal outcomes if not diagnosed and managed promptly(1). The main cause is an iatrogenic injury during pharyngeal instrumentation and commonly present with neck pain, swelling, and subcutaneous emphysema. Many predisposing factors played a major role like difficult instrumentation, pharyngeal infection and old age(2). In our case, we present a patient with prostate cancer who underwent radical prostatectomy and was found to have mediastinal and surgical emphysema.

In this paper, a cloud-level grading comprehensive evaluation model based on fuzzy c-means algorithm is established. The image is binarized by the maximum inter-class variance method to obtain the dim curve. According to the dim curve of the four quadrants, the distribution and thickness of the cloud layer are discriminated. Three attributes of the effective area of the cloud layer, the total amount of clouds, and the thickness of the cloud amount are selected as the characteristic data of the comprehensive evaluation model.

BACKGROUND Salmonella infection is common in tropical countries including Malaysia. It is invasive in immunocompromised and those of extreme ages. It typically presents with gastrointestinal symptoms such as diarrhea, abdominal pain or vomiting. Extra-intestinal manifestations are seen in 30% of salmonellosis cases. These atypical manifestation leads to difficulty and delay diagnosis thus poorer outcome. Pericardium involvement is estimated to be less than 2% of all cases and has mortality rate as high as 50%1. As high as 70% of pericarditis cases were identified to be immunosuppressed2; these include chronic immunosuppressant usage, autoimmune disease, end stage renal failure, malignancy and etc. Herein, we report a fatal case of pyogenic pericardial effusion by Salmonella enteritidis in an immunocompetent adolescent. CASE PRESENTATION A 16-years-old Malay boy was referred from GP to our centre in April 2015 with CXR finding suggestive of pericardial effusion. He had prolonged cough for 8 months, associated with breathlessness and failure symptoms. He had on and off fever but denied gastrointestinal symptom. He had multiple visits to private practitioners and was investigated for Tuberculosis, which yielded negative result. His condition continued to deteriorate. Of note, he had no significant medical and surgical illness. There was no history of contact with tuberculosis patients, recent travelling history or high risk behaviour. Upon admission, he was tachypnea and in shock. His blood pressure was 90/56mmHg with a pulse rate of 102bpm. His JVP was raised and heart sound was muffled. Lung examination revealed reduced breath sound bilaterally with generalized rhonchi. Initial blood investigations revealed leukocytosis with predominant neutrophils (16 x 109/L). ABG showed type 1 respiratory failure. ESR was raised, 100mm/hour. Chest X-ray showed a congested lung field consistent with pulmonary oedema. Bedside echocardiogram revealed a large pericardial effusion with diastolic right atrium and ventricle collapsed, indicating temponade effect. Emergency pericardialcentesis drained…

This paper constructs a self-organizing maps (SOM) neural network model for the anomaly data cleaning in thermal power plant detection. The test data is trained 2000 times so that the vector of each weight is located at the center of the input vector cluster, and the 6*6 competitive network is constructed. The network classifies or eliminates the screening of data, and obtains a healthy sample library that can be used to predict the running state of the machine in the future, achieving a good data cleaning effect.

This paper studThis paper studies the design of professional clothing for high-temperature operation. Based on the temperature distribution inside the garment and outside the human skin, a mathematical model is established to calculate the temperature distribution. For a three layers fabric material, the heat transfer equation for the fabric layer is established. The heat transfer of the air layer between the fabric and the skin is dominated by radiant heat exchange, effectively interpreting the heat transfer mechanism of the air layer, thereby constructing the energy heat balance equation of the air layer. Combined with the initial conditions and boundary conditions, the spatial and temporal dispersion of the finite explicit difference format is performed.

In recent years, the quality of urban atmospheric environment in China has caused widespread concern in the whole society. Improving air quality has become a major content of air pollution prevention and control in China. To do a good job in atmospheric prevention and control, we must investigate and analyze the sources of major atmospheric pollutants and their pollution characteristics firstly. With the acceleration of urbanization, the air pollution situation in Jinan city has become an environmental problem that people are particularly worried about. Based on the monitoring data of Jinan atmospheric environment, this paper analyzed the monthly average concentration values of PM2.5, PM10, NO2 and SO2 in Jinan City from 2015 to 2017. Meanwhile, the main reasons for the air pollution in Jinan City were clarified in detail. Finally, air pollution control strategies were proposed corresponding the aspects of pollution sources, topography and meteorological conditions, rational planning, environmental supervision capabilities, environmental awareness, and practical treatment technologies in Jinan City. These measures can provide a theoretical basis for relevant leading departments to build a beautiful city.
